94 camry horn trigger?

I cant seem to find the horn trigger on the steering column. I foudn a green and black wire coming from the steering wheel but when i hit it with a test light it doesnt honk or anything. Unless im not at the steering column harness? The black connector with two seperate plugs ? If this is in correct please inform me where the right harness is thanks

Its the small 20 guage wire, not the larger on. Yes you have the correct plug

yep thats the wire im on

does your horn work?     does it work with the key OFF. ON ?  Have you hooked your horn output from the unit your installing....use a relay!
